Answer:

14

Step-by-step explanation:

STEP1:

1 Simplify — 3

Equation at the end of step1:

1 (x - 4) - (— • (6x - 54)) = 0 3

STEP2:

STEP3:Pulling out like terms

 3.1     Pull out like factors :

   6x - 54  =   6 • (x - 9) 

Equation at the end of step3:

(x - 4) - 2 • (x - 9) = 0

STEP4:Equation at the end of step 4

14 - x = 0

STEP5:

Solving a Single Variable Equation:

 5.1      Solve  :    -x+14 = 0 

 Subtract  14  from both sides of the equation : 

                      -x = -14

Multiply both sides of the equation by (-1) :  x = 14

Find an equation of the line through (3,6) and parallel to y = 4x - 7.
FromTheMoon [43]

Answer:

y=4x-6

Step-by-step explanation:

Okay, to do this we must understand what parallel means.

parallel means that that one line will NEVER touch the other. In order for this to happen they must be increasing (or decreasing) by the SAME rate. I.e the slope of your line must be the same as the lin in question thus our equation looks like,

y=4x+c.

Now lets find c.

To do this, plug the point (3,6) into the equation

6=4(3)+C

6=12+C

-6=C

Thus now that we know C, our equaiton is

y=4x-6

The measure of angle A to the nearest tenth of a degree is: A 18.5 B 19.5 C 20.5
Andrew [12]

Answer:

B


Step-by-step explanation:

<u>This is a right triangle as shown by the right angle.</u>

  • The side opposite the right angle is the hypotenuse, which is 9.
  • The side opposite angle A is 3.

So we have the opposite of A and the hypotenuse.

The trigonometric ratio that relates opposite side to hypotenuse is SINE.

sin\theta=\frac{opposite}{hypotenuse}

Since, we need angle A, \theta is A, opposite side is 3, and hypotenuse is 9, we substitute:

sinA=\frac{3}{9}\\sinA=\frac{1}{3}

<em>To solve for the angle, we use our calculator and find the inverse sin of \frac{1}{3} :</em>

A=sin^{-1}(\frac{1}{3})\\A=19.47

<em>Rounding to nearest tenth of a degree:</em>

A=19.5

B is the right choice.
